How To Prevent Air Duct Contamination
Whether or not you choose to have your air ducts cleaned is a personal choice. But you can commit to a good preventative maintenance program to minimize air duct contamination. This will prevent dirt, grime, and other biological particulates from entering your air supply.
To prevent dirt from entering your duct work:
Use the highest efficiency air filter recommended by the manufacturer of your heating and cooling system. Your HVAC technician can help make suggestions if you aren’t sure.
Change your filters on a regular basis. At a minimum, once a quarter or at the beginning of each season. The more active your household, the more you should up the replacement timeframe.
Be sure you are using the correct air filters and that air cannot bypass the filter and move around through gaps in your equipment. This can lead to inefficiencies and allow contaminated air to enter your ducts and air supply.
Be sure to hire the best when it comes to maintenance and repair of your HVAC equipment. During regular maintenance visits, they should be cleaning your cooling coils, and drainage pans too.
During construction or renovation, be sure to seal off supply and return registers and do not operate your heating and cooling system until after you clean up all the dust.
Vacuum your home regularly. Use a high-efficiency vacuum with the highest efficiency filter bags your vacuum can take.
If you have humidification equipment, be sure to operate and maintain as recommended by the manufacturer.
While dirt and particulates in your duct system are potential problem sources, moisture can be even more disastrous. Controlling moisture is the most effective way to prevent biological growth in air ducts. Clean up leaks or water damage right away. If you suspect water damage, don’t wait, contact your HVAC technician immediately. Controlling moisture can prevent costly expenses and keep you healthy too.
